High-Accuracy Seawater Refractometer
Offers exceptional accuracy for measuring the absolute salinity of seawater at a temperature of 25C/77F
Most refractometers used within the aquarium hobby are not specifically designed for reef aquariums and use an algorithm for the measurement of brine (NaCl - rather than seawater) and at a temperature of 15C/59F rather than 25C/77F. Thus a measurement deviation of up to 1.5ppt is possible, which can have a significant adverse effect on coral growth and colouration.
